What Your EV Battery Warranty Actually Covers

“Lifetime battery warranty” sounds simple. But what does it actually mean?

EV battery warranties can have different rules depending on who owns the car, how it is used, how long it has been registered, and how much battery capacity has degraded.

In this video, Garage Decoded breaks down what an EV battery warranty actually covers, how lifetime warranties work, what happens when the car is sold, how private and commercial use can affect coverage, how manufacturers measure battery degradation through State of Health, and what can happen when a battery actually falls below the warranty threshold.

We also look at the conditions hidden inside the warranty terms because the headline number is only part of the story.
